Following some earlier reports saying that HTC was working on a new smartphone with bigger display measuring as much as 5 inches, the Taiwanese smartphone has indeed introduced HTC J Butterfly with a 5-inch 1080p display in Tokyo Wednesday.

HTC J Butterfly, which is expected to be released in December on AU/KDDI, is claimed to be the first announced phone featuring a 5-inch, 440ppi full-HD "Super LCD 3" panel. The display comes with a resolution of 1920 x 1080 that gives it a pixel density of 440 ppi.

Although the Butterfly features a bigger display with a dimension of 143 x 71 x 9.1 mm, it is only slightly bigger than the One X that comes at a dimension of 134.4 x 69.9 x 8.9 mm. It weighs 140g, 10g more than the One X.

A successor to HTC J, the HTC J Butterfly runs on Android 4.1 Jelly Bean and is powered by a quad-core 1.5GHz Snapdragon S4 Pro APQ8064 processor. It has 2GB of RAM and an 8-megapixel camera with an f/2.0 lens.

According to The Verge, the most eye-catching feature of HTC J Butterfly is its full Super LCD 3 screen.

“The Super LCD 2 seen in HTC's previous flagship One X was arguably the best panel on the market, but we think its successor is the new champion,” said the report.

The only thing about HTC J Butterfly that could not be up to the mark is its 2,020mAh battery. With the super dense LCD and high-end processor, it will be interesting to see how the phone’s battery performs.

The HTC J Butterfly will be sold in three colors: red, black and white.
